I T all whom it may concern:

'tates sprocket wheel 21, this drives chain there are no combination units. Our arrangement is especially adapted to slicing machinessuch as shown in the patent issued to us' June 5th, 1917,#1,22s,509. It however, can be adapted to any make of machine used for slicing purposes where it is desired to drive by power or by hand.

- Our invention is illustrated more or less diagrammatically in the accompanying drawings of which- I v Figure 1 is a diagram showing the driving connection between the motor and slicin machine elements.

ig. 2 is a plan of the same. 7 i .The numeral 1 represents the base of an ordinary slicing machine equipped with the standard rotary knife 2.

Mounted .at some convenient place in the slicing machine is a motor 3 of any standard make;

Mounted on the outside of one of the bearings 4 of motor 3 is a gear housing 5 which contains a chain of gears and an overrunning clutch through which the motor drives the shaft 13. f

Mounted on the end of sprocket wheel 19 .which is connected by means of a chain 20to a sprocket wheel 21 carried by the driving shaft 22 0f a standard slicing machine. This shaft 22 is provided with a sprocket 23 which connects with a sprocket 24 by means of a chain 25 for driving the slicing machine knife 2.

Mounted on shaft 22' is a bevel gear 26 meshing with a bevel gear 27 carried by a A Specification of Letters Patent.

Beit known that we, K. l-Ioona id 'WALLAoE B. lVOLFF,-citizens of the United- -to transmit the power to t .of the slicing machine. It will thus be seen,

their different diameters, any desired pre-v determined relative speed between the motor, handwheel and cutting knife can be obtained by changing sprockets from one shaft to the other. The operation of the, the following is aspeci- 1 If it is'desired to' turn the device' thus-far f011 --1, L

'achine, by

hand, the hand wheel 29 is'rotated in aclockwisedirectiom Theipower is transmitted through gears'27 and 26 'to the ma chine driving shaft. 22. Sprocket 23 com" veys the" power'to chain 25 which carries itto' sprocket 24 mountedon the cuttingknife 2, thus driving the machine." 1

On account of the fact, that shaft 22 1- 20,- sprocket wheel 19 and shaft 13. The

overrunning clutchis so arranged on the shaft that the rotation thereof in the direc- .t on' in which'it is operated .by the hand wheel causes it to disconnect from the motor train of gearing. This makes it. possible to operate the machine by hand without makmg any shift or. disconnection. Now if it is desired to drive. themachine by the motor, the current is turned. on .and the power is transmitted through the chain of gears and overrunning clutch in the lproper direction e driving train that it is possible to operate the slicing machine by either means or by both means simultaneously and that it is not necessary to throw in or to throw out devices to disconnect either one of them. The advantages of this in a slicing machine are many.

It is very often desired to cut material until a 'certain weight has been reached and by operating a machine electrically, it is possible to do the cutting easily and rapidly. It might be found that there was not.q uite a suflicient'amount. of material cut to reach the desired weight when the current was snapped off and the machine stopped; It

would therefore only be necessary to grasp the hand wheel and ope'rate the machine for a short period by hand until the proper amount had been cut.

Customers often buy in small quantities and the cutting can be accomplished by hand ractically'asquick as electrically.

' There ore, the machine would be operated electrical trouble. 'VVe therefore mountmo tor 3 'onabracket 30. This makes it po'ssible-to remove the electric unit without dis arranging any of the hand driving unit and the machine can still remain in servlce while electrical repairs are being made.

V We claim as our invention:

- hen the machine is driven electrically, it is advantageous to have this handle out of the-way. and'therefore by grasping it and pulling sleeve 37 out of recess 42, the handle in the drawings'z-i' can beswung down into; the position shown 1. A transmission mechanism comprising a motor," a reduction gear unit, unitary 'therewlth; a power-transmitting connection connected to said gear unit, including interchangeable gearielements and an overrunning clutch; and a hand-operated device geared to the transmitting connection at a point in the connection more remote from the motor than the clutch.

2. A transmitting mechanism comprising a.-motor, a reduction'g'ear unit, :unitaryi therewith; a power transmittingconnection connected to said gear unit, including inter- '.chang'eable gear elements; and a hand op? erated device geared to the transmitting connection. I

' 3. In' a slicing machine a "transmission mechanism comprising a motor; a'reduction gear unit, a power transmitting connection connected to said gearunit; including inter-' changeable gear elements; an ioverrunning clutchand a hand operating device geared to the transmitting connection at a pointin the connectionmore remote from the motor than the clutch.
